Jiri Prochazka’s unorthodox training methods have fans puzzled ahead of UFC 320

Prochazka is putting a focus on his breathing techniques as he gets ready for the title eliminator at UFC 320.

In one session, the 32-year-old was seen using a nose peg to limit his oxygen intake.

He also did several 40-second sprints with his mouth closed, not taking a single breath during each run.

The unusual approach left fans scratching their heads and laughing in equal measure.

One fan wrote: “Everything other than learning how to defend.”

A second added: “Is there anything more Jiri than this?”

A third commented: “This is one of the most bizarre things I’ve ever seen lol. Genuinely have no idea how this would help him at all.”

“What could possibly be the benefit of this?” another fan asked.
